Acoustic Transducer Mounting via Through-Hole Connecting Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The vibrated body of musical instruments, such as soundboards, undergoes dimensional changes and deformation due to temperature and humidity influences, causing the vibrating unit of the acoustic transducer to displace perpendicular to the magnetic-path forming portion, leading to noise and potential physical contact, which can disrupt the vibration process.
Innovation Solution
An installation structure for the acoustic transducer with a magnetic-path forming portion having a through-hole, a vibrating unit that protrudes away from the vibrated body, and a connecting unit that passes through the hole to increase the distance between attachment points, reducing displacement and preventing inclination of the vibrating unit relative to the magnetic-path forming portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vibrating unit is fixed close to the magnetic-path forming portion to ensure stable vibration transmission, then the vibration efficiency is improved, but the displacement caused by vibrated body deformation increases, leading to noise and potential contact between the vibrating unit and magnetic-path forming portion
Solution Approach 1:
The patent introduces a connecting unit that extends in a direction perpendicular to the vibration direction, creating a spatial buffer zone. This dimensional extension allows the vibrating unit to remain close to the magnetic-path forming portion for efficient vibration transmission while the connecting unit absorbs perpendicular displacement caused by vibrated body deformation, preventing contact and noise
2Object-affected harmful factors
If the distance between the vibrating unit and vibrated body is increased to reduce displacement impact, then the displacement tolerance is improved, but the vibration transmission efficiency decreases
Solution Approach 1:
The patent divides the connection path into two functional segments: the connecting unit that handles perpendicular displacement and the vibrating unit that handles vibration transmission. This segmentation allows each component to be optimized for its specific function - the connecting unit for displacement tolerance and the vibrating unit for vibration efficiency - without compromise
3Adaptability or versatility
If the vibrating unit protrudes from the magnetic-path forming portion to allow connection to the vibrated body, then the installation flexibility is improved, but the risk of physical contact between the vibrating unit and magnetic-path forming portion increases when displacement occurs
Solution Approach 1:
The patent introduces the connecting unit as an intermediary component between the vibrating unit and the vibrated body. This mediator absorbs the perpendicular displacement through its length, allowing the vibrating unit to protrude for installation flexibility while preventing contact with the magnetic-path forming portion through the buffer provided by the connecting unit
